Please tell me what this line do->

while(f1.read((char*)this,sizeof(park)));

Please tell what's the use of WHILE and THIS in this statement.

The while loop will overwrite the data of whatever this points to until it reaches end of file or any other error.

It would be a big surprise if that does not lead to crash.
